Inverse nodal problem for differential pencils

On a lipschitz stability problem for p-Laplacian Bessel equation

“…Nodal length of this problem is denoted by l n j = x n j+1 x n j for j = 1; 2; :::; n 1: Using these type nodal datas, some uniqueness and reconstruction results for di¤erent type of operators have been expressed by several authors (see [21], [22], [23], [24] ). …”

An inverse nodal problem for differential pencils with complex spectral parameter dependent boundary conditions

“…Independently, Shen studied the relations between the nodal points and the density function of string equation in 1988 [9]. Later, many authors have studied inverse nodal problem for different operators (see [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20]). …”

Impulsive Diffusion Equation on Time Scales

“…Then, Gasymov and Guseinov [24] determined the diffusion operator from spectral data in 1981. Fragela [25] authors (see [33][34][35][36][37][38][39][40][41][42]). …”
